So I have this theory that if I break down my current addiction of Porn into addiction with less harmful things.I could abstain from PMO. I recently made it past one week but that was because I was so busy watching an anime with the name Steins;Gate I didn't even think about PMO. My personal best of 3 weeks was also when I was watching an anime called Naruto Shippuden. But the problem is that I always end up relapsing.ALWAYS.
I see what you are pointing at here. It's actually seeking joy/entertainment/dopamine from other sources other than porn. So yea this will definetly work. This will only help you get distracted though for enough time, but at some point, you will have to build solid habits that will give you permanent joy.
Also try to take up exercises. Some intense exercises can really drain you of your energy and at that point you won't even want to fap
